Corrosion Resistant Valve Parts
Refractron Technologies Corp. is a leading manufacturer of technical ceramics. Products include both controlled porosity and densely structured ceramics designed to meet requirements specified by our customers for:
- Durability
- Chemical
- Corrosion
- Wear resistance
- Toughness
- Density
The range of dense structural ceramics using proprietary zirconia ceramics includes custom blended ceramic alloy powders formed by isopressing or extrusion to meet customer specifications. Refractron's zirconia is offered in two materials Magnesia Partially Stabilized Zirconia, Mg-PSZ and Yttria Tetragonal Zirconia Polycrystal, Y-TZP. Refractron's structural ceramic zirconia materials provide excellent erosion, corrosion and abrasion resistance along with temperature resistance, fracture toughness and strength. These ceramic alloy components are used in extreme service applications that take advantage of their superior wear and corrosion resistance. Numerous applications for these materials are in the chemical and petrochemical industry providing economic payback in the way of reduced maintenance and down time. Zirconia is also becoming the material of choice for components in healthcareapplications.
This dense structural ceramic material is usually precision ground using conventional diamond cutters and wheels. Machines used for precision grinding include:
- surface grinders
- CNC milling machines
- jig grinders, center less grinders
- CNC lathes
- ID grinders
Refractron Technologies Corp's Magnesia-partially Stabilized Zirconia (MgPSZ) is the right choice in choosing an advanced ceramic valve trim component where the traditional metal alloys fail. Valve trim components made with Refractron's Zirconia have superior abrasive resistance as compared to carbon steel, 316 Stainless, D2-Steel, Stellite Alloy 6, and Tungsten Carbide. In addition, zirconia is inert to virtually all acids, bases, solvents, and other corrosive slurries and fluids and it resists scaling or sticking.
Refractron's MgPSZ zirconia ceramic lined valve components will allow you to extend your valve component service life. Enabling you to improve operating efficiencies, reduce maintenance costs, and minimize downtime with less frequent valve repairs. Our zirconia is extremely strong, has superior toughness, and excellent abrasion resistant. Additionally we use a proprietary manufacturing process, starting with the highest purity raw materials that result in a chemically superior zirconia product as compared to the competition. This translates into superior chemical stability of the ceramic trim components in operation when subject to the corrosive liquids and slurries in applications like: lime slurries, sodium hydroxide and acids like hydrochloric, nitric and sulfuric.
Additional structural zirconia ceramic components produced by Refractron include:
- valve pump liners
- sleeves
- pistons
- precision ceramic balls
- spools
- press tooling
- extrusion tooling and wear plates
Other specialty porous ceramic products include filters, diffusers and adsorbent filter/drier cores for refrigeration applications, dispersion parts, vacuum chucks, inkpads and gas probes. We work closely with our customers to define their needs and the requirements of each specific structural ceramic valve application. Our engineering and sales team is great at attacking technical design and process problems, then customizing an innovative solution using our broad range of advanced industrial ceramics.
